怎么检查Oracle Advanced Security Option 是否被安装上？
解决方案：
从Oracle 8i开始，ASO ships with Enterprise Edition release of Oracle。在Oracle 8.0及其以前，ASO在单独的CD里边。
OUI的企业版安装包括ASO option。为了使用ASO特性，ASO必须在client和server都安装。ASO必须在企业版软件中使用，并且需要license。
在unix和windows平台下，可以通过OUI（$ORACLE_HOME/oui/bin/runInstaller）中的“installed products”来检查，如下图所示：
在unix平台下，可以使用adapters命令来检查：
[[email protected] ~]$ which adapters
/u01/app/oracle/product/11.1.0/db_1/bin/adapters
[[email protected] ~]$ adapters
Installed Oracle Net transport protocols are:
IPC
BEQ
TCP/IP
SSL
RAW
SDP/IB
Installed Oracle Net naming methods are:
Local Naming (tnsnames.ora)
Oracle Directory Naming
Oracle Host Naming
Error!!! Oracle Names Server Naming is not completely installed!
Installed Oracle Advanced Security options are:
RC4 40-bit encryption
RC4 56-bit encryption
RC4 128-bit encryption
RC4 256-bit encryption
DES40 40-bit encryption
DES 56-bit encryption
3DES 112-bit encryption
3DES 168-bit encryption
AES 128-bit encryption
AES 192-bit encryption
AES 256-bit encryption
MD5 crypto-checksumming

[[email protected] ~]$
Please note the line Error!!! Oracle Names Server Naming is not completely installed! is expected behavior for the adapters command from version 10g onwards. This is due to the fact Oracle Names is no longer shipped.
If after installation, Net Manager does not show Advance Security options, see Note 156345.1 Oracle Net Configuration Tools Do Not Show ‘Advanced Security‘
Oracle product development has decided that starting with Oracle 11g Oracle Advanced Security Option will be installed by default when installing Enterprise Edition . There is no way to uninstall or to install it. The reason behind this is that Oracle Advanced Security Options are integrated at network adapter level and it is not appropriate to tweak network adapters after database installation .
